WASHINGTON - Secretary of State Hillary Clinton unveiled an ambitious US blueprint on how to realise the vision of an AIDS-free generation, aiming to see virtually no babies born with HIV by 2015. “Scientific advances and their successful implementation have brought the world to a tipping point in the fight against AIDS,” the 54-page document says. Calling AIDS “one of the most complex global health issues in modern history,” she wrote in the foreword that challenges still exist, pointing to the 1.7m people who die every year from AIDS-related illnesses. But she stressed that developing AIDS after becoming infected with HIV is no longer an automatic death sentence, and major advances have been made in treatment and prevention.
